The configuration that determines how the history is recorded.
Notifies this instance that something is referencing it.
The new value of the reference count.
Erases the trail history.
Returns the name that was assigned by the call to the setLoggingName method.
An object is a zombie if it has been released by all who have held references. In some cases it may be possible to recycle a zombie.
Notifies this instance that something is dereferencing it.
The new value of the reference count.
Renders the mesh in its historical positions and attitudes.
This method is for use within constructors.
Immediately after a call to the super class constructor, make a call to setLoggingName. This will have the effect of refining the name used for reporting reference counts.
This method has the secondary purpose of enabling a tally of the number of classes in the constructor chain. This enables the runtime architecture to verify that destructor chains are consistent with constructor chains, which is a good practice for cleaning up resources.
Notice that this method is intentionally protected to discourage it from being called outside of the constructor.
This will usually be set to the name of the class.
Records the Mesh variables according to the interval property.

Records the position and attitude history of a
Meshallowing theMeshto be drawn in multiple historical configurations.This class is refererce counted because it maintains a reference to a
Mesh. You should call thereleasemethod when the trail is no longer required.// The trail is constructed, at any time, on an existing mesh. const trail = new EIGHT.Trail(mesh) // Configure the Trail object, or use the defaults. trail.config.enabled = true trail.config.interval = 30 trail.config.retain = 5 // Take a snapshot of the ball position and attitude, usually each animation frame. trail.snapshot() // Draw the trail during the animation frame. trail.draw(ambients) // Release the trail when no longer required, usually in the window.onunload function. trail.release()
